To prevent future Bidens
you need to stop relying on the president for any agenda you might have... laws are passed on Congress and most failures of agendas or plans cna be traced back to congress and poor leadership by the president only when they have control over the House/Senate.
the progressive platforms pushed by Sanders and AOC have had no basis in reality or compromise so they had a snowball's chance in hell of ever being passed.
to be fair are you really that shocked election promises of the far left were unable to pass?
